Smart sensing for real-world use

• Photoelectric sensing detects smoldering fires quickly, while an electrochemical CO sensor delivers fast carbon monoxide readings.
• Battery-powered operation keeps the system active during power outages, adding flexibility for different living spaces.
• Standalone, space-saving design fits neatly on walls or ceilings without dominating the room.

Clear status at a glance

A large LCD display shows current smoke or CO readings when conditions warrant. In standby, the screen stays off and the green LED blinks every 60 seconds to conserve battery life.

• Red LED indicates active smoke or CO alerts for immediate recognition.
• Yellow LED flags faults or sensor issues to guide quick checks.
• Green LED blink in standby confirms the unit is powered and ready.

Simple, reliable operation

The built-in test button makes it easy to verify function without special tools. If the battery gets low, you’ll hear an alert and see a red LED flash to prompt replacement.

• Test button allows quick, routine checks.
• Low battery triggers both sound and red LED feedback for clear cues.

Install and maintain with ease

Mounting is straightforward on a wall or ceiling using the included screws. The combo units are designed for simple setup and ongoing battery-powered reliability across rooms like the kitchen, living areas, bedrooms, or office spaces.

What you get

• 2 detectors in the pack

Use cases and note

Place these units where smoke or CO concerns are most likely—near living areas, kitchens, basements, or hallways. They offer informative feedback and alerting behavior designed to support awareness and timely actions, without promising guaranteed results.
